Question

StreamResourceInfo sri;
sri = App.GetResourceStream(new Uri("WebBrowserIsoStorage;component/Images/textmate.jpg", UriKind.Relative)); 
using (BinaryReader reader = new BinaryReader(sri.Stream)) 
{ 
    using (BinaryWriter writer = new BinaryWriter(imageStream)) 
    { 
        while (sri.Stream.Position < sri.Stream.Length) 
        { 
            writer.Write(reader.ReadByte()); 
        } 
    } 
} 

What does the WebBrowserIsoStorage; in the path mean (line 2)?

Answer 1

That uri string is a relative Pack UrI (see Table 2 in the linked page for a similar example).

The first part (WebBrowserIsoStorage) is the assembly in which the resource (the textmate.jpg image) lives. The second part is the path to the resource within the assembly.
